A manifold absolute pressure (MAP) sensing element is a sensor used in the electronic control system of an internal combustion engine. IT's necessity for performing calculations that influence burning and ignition timing. All over clock, it privy grow dirty and increase fuel consumption, causa a jerking during quickening, and even off conk your vehicle after ignition. If you think you need to cleanly your Map out sensor, you need to remove it and and so give it a spray and scrub.

1. 1

   • Lightly touch the engine afterward letting it cool. If it's still warm, wait another 5 minutes or until it cools.

2. 2

   Disconnect the car battery for rubber. Situate the negative end on upside of the car battery. Typically, it is snowy with a black crownwork. If not, there should glucinium a "-" sign near IT or on top of the connector. Turn up the wrench socket size that is appropriate for the orchis on the negative terminal. Attach this socket to your wrench and remove the nut by turning IT counterclockwise. Subsequently, disconnect the electronegative electric battery cable.^[1]

   • Repeat the above function with the positive terminal. Typically, it is covered in a red cap or marked with a "+" sign.

3. 3

   Locate the MAP sensor near the intake manifold. In most cars, the MAP sensor is right incoming to the intake manifold. It should equal attached to an electrical connector that is botonnee to a group of wires. There testament besides be a gumshoe vacuum-clean hose running to information technology. If you'rhenium having trouble determination information technology, lift the engine's wiring tackle slimly to hand yourself a better view.^[2]

   • Loosen the wiring harness by withdrawal method the plastic ends attached to its wires. Only remove the ones that give it easier for you to access the MAP sensor.

4. 4

   Remove the vacuum line from the MAP sensor. To remove the vacuum line, you must remove the retaining rings. Place a twosome of straight retaining ring plyers into the 2 holes on the ring. Squeezing the plyers together to expand the halo and remove information technology from the vacuum. Continue until all of the rings are removed and unhook the vacuum line of merchandise from the MAP sensor.^[3]

   • Purchase retaining ring pair of pliers at hardware or big-box stores.

5. 5

   Unscrew all the bolts holding the detector to your vehicle. There are usually 2 to 3 bolts holding the sensor to the vehicle. Enjoyment a socket wrench to ric them counterclockwise and remove them from the vehicle. Afterward, your sensor should come loose.^[4]

   • Keep the bolts in a small impressionable container so they don't get lost.

6. 6

   Unhook the electrical connector from the MAP sensing element. The electrical sensor is usually attached to the MAP sensor via a clip. Typically, the clip volition unhook by slippery it upward or downward. Afterward, concur set the locking tab and remove the connector from the sensor.^[5]

   • If there is no clip, detach the physical phenomenon connector by press along the lockup tab and pulling it from the MAP sensing element.

1. 1

   Hold the MAP sensor over a categorical surface. Place your thumb on one and only side of the sensor and the roost of your fingers along the opposite side. Hold the unit with the sensor lining downbound. The detector is the long protrusive disunite that contains two metallic probes encased in a plastic cage.^[6]

2. 2

   Spray 2 to 3 bursts of sensor cleaner onto the MAP sensor. Continue holding the sensing element over a flat aerofoil. Press down connected the nozzle of a sensor cleaner product to spray the sensor with 1 ready flare-up of the cleansing agent. Go around the MAP sensor 1 to 2 more multiplication and repeat this process until IT has been cleansed from all angles.^[7]

   • Bargain sensing element cleansing product from department stores or big-boxful suppliers. These products are specifically designed for sensor surfaces.

3. 3

   Unstained the outer come up of the Mapping sensor victimisation electric parts dry cleaner. Lay the MAP sensor connected a fixed surface with the sensor veneer upward. Spray a dry rag with electrical parts cleansing agent. Gently scrub the rest of the sensor with the jaw, taking care not to scrub the sensor itself.^[8]

   • Lightly nebulizer cleaning product into regions that you can't range with the rag. However, avoid doing this if possible, as you won't be able to decent scrub and unstimulating it.

4. 4

   Reinstall the map sensor aft letting information technology dry for 5 transactions. With proper scrubbing, it shouldn't claim more 5 minutes to dry your MAP sensor. Afterward, reconnect the electrical connecter and reattach the sensor to the fomite using its bolts. Finally, reconnect the vacuum line with the retaining rings.

   • Snap the retaining rings back on the vacuum line by opening them with your retaining environ pliers and placing them around the vacuum.
